Features & Highlights

• Plug-and-Play Simplicity — No configuration or setup is needed. All ports auto-negotiate speed and duplex.
• Partial PoE Support — 12 PoE ports with 100 W budget for powering devices like IP phones, access points, or cameras.
• Full Gigabit Throughput — All ports support Gigabit speed, so there is no throttling of your data traffic.
• Energy Efficiency — IEEE 802.3az (Energy Efficient Ethernet) supports putting links into lower power mode during inactive periods.
• Smart Diagnostics – Includes loop detection and cable diagnostics, allowing issues to be identified quickly, even without a management interface.
• Operating Silently: Because of its fanless design, it is suitable for use in offices and other settings where noise levels must be kept low.
• It can be installed in a rack (1U) or on a desktop/wall, depending on your needs.
• Cisco Reliability and Guarantee: To provide your peace of mind, Cisco built this device with a limited lifetime hardware warranty.

Use Cases / Ideal Scenarios

• Small Business / Branch Offices — Especially where IT personnel are minimal or nonexistent
• PoE-Powered Devices — Perfect for powering IP phones, wireless access points, or thin security cameras
• Workgroup Expansion — Adds Gigabit ports to an existing network easily
• Quiet Environments — Ideal for offices, reception areas, or meeting rooms that need quiet hardware
• Plug-and-Play Deployment — Ideal choice where you need fast deployment with no lengthy configuration

Technical Insights

• Although this is an unmanaged switch (you can’t configure it using GUI or CLI), the CBS110-24PP-UK is smart internally:
• It negotiates the best speed (10 / 100 / 1000 Mbps) and whether the connection is full or half duplex automatically.
• PoE feature saves the use of external power supplies for phones and access points, among other devices, reducing cabling complexity.
• It uses store-and-forward switching, which helps in dropping damaged packets and improving network integrity.
• Loop detection and cable diagnostics also automatically take place in the background, enabling even non-IT users to detect cabling issues early.
• It also has support for jumbo frames (up to ~9,216 bytes), which is handy for large file transfers or virtualization traffic.
• Power consumption is also kept in check via IEEE 802.3az, which reduces power consumption during periods of inactivity.
